BICYCLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 663,913, dated December18, 1900.

Application filed August 4, 1900. Serial No. 25,958. (No model.)

Our invention relates to bicycle-brakes.

which have coasters attached thereto; and our object is to make such acombination in a coaster-brake that it can be firmly attached to thefront forks, can be applied instantlywith one or both feet, and doesaway with much of the wear on both tire and brake.

Oursimple combination is formed by mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a side elevation, slightlyin perspective, of the front forks and part of the frame and front wheelof a bicycle, showing ourbrake in position for braking on the wheel andin dotted outline as when released. Fig. 2 is a detail view of ourspool-shaped roller-v brake in bridle. Fig. 3is a detail view of clipfor front fork and coaster-step. Fig. 4 is a detail of ring forattaching spring to fork.

Similar numerals refer to similar parts in the several views.

10 is the bicycle-frame.

11 is the front fork, and 12 the wheel.

13 13 are clips, which are attached to each fork by bolts 14 15, thedouble draw of these bolts giving a specially tight clamp on the fork,so that the clip will not slip. The clip extends out on one side incoaster-step 16, and the rear ends of the clip 17 17 are pivotallyattached to side bars 18 18.

19 is a spool-shaped roller-brake revolubly mounted in the ends of sidebars 18 18 and in bridle 20, which bridle is connected with the top offork 11 by ring 22 and spring 21, as shown. Fig. 4 shows ring 22 withspring 21 broken off.

23 23 are swinging side steps attached to bars 18 18 on each side, whichare always in position for use, since they always hang downward Whateverthe position of the brake. By the simple pressure of the foot of therider on one step 23 or of both feet on both steps, if greater power isdesired, roller-brake 19 is pressed on wheel 12, the foot bringing thebrake down from the position shown in dotted outline, and when thefoot-pressure is released the brake is instantly drawn up out of the wayby spring 21.

We claim as new In a bicycle coaster'brake, metal clamps encircling thefront forks of a bicycle being formed into coaster-steps on the outersides and having rear extensions, bolts through said coaster-steps andbolts through said extensions to doubly secure the clamps on the forks,side bars pivotally attached to said extensions, steps pivotallyattached to said side bars and a concave roller brake mounted therein, abridle pivoted to said bars having a coiled spring and clip to hold therollerbrake 0d the wheel, shown and described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
